Cross multiply
Answer:
k = 4
Step-by-step explanation:
To solve ANY proportion, you can cross multiply. For example, in this case, you can multiply 7 x 32 and k x 56. Remember, a proportion is always equal, so 7 x 32 = k x 56. That means 224 = 56k. Which means k = 4. Hope that helped!

How many boxes with a Length/Width/Height of 1/4, 1/4, and another 1/4 would fit into a box with a Length/Width/Height of 3 1/4, 3, and 3 3/4?
9514 1404 393
Answer:
2340 small boxes
Step-by-step explanation:
Each unit of measure used for the large box will contain 4 of the smaller boxes. So, in terms of small boxes, the dimensions of the larger box are ...
(3 1/4)/(1/4) = (13/4)/(1/4) = 13 . . . length
3/(1/4) = (12/4)/(1/4) = 12 . . . . . . . width
(3 3/4)/(1/4) = (15/4)/(1/4) = 15 . . . height
Then the number of small boxes that would fit is ...
length × width × height = 13×12×15 = 2340
2340 cubes of size 1/4 will fit into the larger box.

The correst angle measures in the triangle ABC is that m∠BAC=72° and ∠BCD=108°.
What is isosceles triangle?An isosceles triangle is a triangle which is having two sides equal to each other.
How to determine angles?Firsty we have to find the value of x in the angles. We have been given that the triangle is isosceles because two sides are equal to each other and we know that angles opposite to two equal sides are also equal to each other.
So,
(4x+16)°+2(5x+7)°=180°
4x-16+10x+14=180
14x-2=180
14x=180+2
14x=182
x=182/14
x=13
Putting the value of x.
∠BCA=5x+7
=5*13+7
=65+7
=72
∠ABC=4x-16
=4*13-16
=52-16
=36
∠BAC=180-36-72
=180-108
=72
∠BCD=180-∠BCA
=180-72
=108°
Hence the correst angle measures in the triangle ABC is that m∠BAC=72° and ∠BCD=108°.

Step-by-step explanation:
Anna and Bobie joined two different swimming classes at the same time.
Anna's swimming school charged an initial amount of $70 and Bobie's charged $250. Their monthly
fees were different.
The total amount paid for in the first t months is given by (PA) for Anna and (PB) for Bobie.
Anna paid $120 and Bobie paid $264 in total for the first two months, but after some months, they
found that they have paid the same amount in total.
After how many months will their total payments be the same and how much will it be?
Answer:
It would be 10 months for the price of $320.
Step-by-step explanation:
First we need to find how much Anna's swimming charge and Bobie's charge is.
PA=70+t The price of the month equals to the starting fee and monthly charge
120=70+2t The price of 2 months times the monthly charge
50=2t
25=t is Anna's monthly charge
PB=250+t is Bobies starting price and monthly charge
264=250+2t is the month charge for Bobie after 2 months
14=2t
7=t is Bobie's monthly charge
70+25x=250+7x We need to find x which is what month will satisfy both equations
25x=180+7x Subtract 70 from both sides
18x=180 Subtract 7x from both sides
x=10 divide 18 from both sides
Now we have the months that satisfy both equations we need to find the total price that matches with it. So we plug it back into both equations.
PA=70+25x PB=250+7x
PA=70+25(10) PB=250+7(10)
PA=70+250 PB=250+70
PA=320 PB=320
what is y intercept in the table
Which is the correct answer?
Answer:
The correct answer is y = 12x + 9
Step-by-step explanation:
There is a formula called y = mx + b where m is the slope and b is the y-intercept
The y-intercept is 9 so y = mx + 9
The slope is 12/1 or just 12 so y = 12x + 9

If you study an extra 10 hours a week for a year (52 weeks) and you earn a four-year scholarship valued at $50,000, what is your hourly return on your investment in study time? (Round to two decimal places)
Answer: $96.15
Step-by-step explanation:
If you study an extra 10 hours per week, for 52 weeks, in total you studied 52 times 10 hours, this is:
52*10 h = 520h hours.
Now, for these 520 hours of hard work, you earn a scholarship valued (in total) at $50,000.
Then how much is worth each one of these 520 hours?
Let's take divide the value of the scholarship evenly into the 520 hours:
$50,000/520h = $96.15.
This means that the hourly return is $96.15

The probability that a 22-year-old female in the U.S. will die within one year is approximately 0.00044. If an insurance company sells a one-year, $30,000 life insurance policy to such a person for $435, what is the company's expectation? (Round your answer to the nearest dollar.)
Answer:
The value is [tex]E(X) = \$ 421.6[/tex]
Step-by-step explanation:
From the question we are told that
The probability that a 22 year old female in US will die within one year is p= 0.00044
The outcome if she dies within one year is that the company losses $30,000
Generally the probability that a 22 year old female in US will live more than one year is
[tex]q = 1 -p[/tex]
=> [tex]q = 1 -0.00044[/tex]
=> [tex]q = 0.99956[/tex]
The outcome if she lives more than one year is that the company gains $435
Generally the the company's expectation is mathematically represented as
[tex]E(X) = -30000 * p + 435 * q[/tex]
The negative sign shows that the company is loosing the fund
So
[tex]E(X) = -30000 * 0.00044 + 435 * 0.99956[/tex]
=> [tex]E(X) = \$ 421.6[/tex]
In Terrance County, 85% of eligible voters are registered to vote, and
government records from a recent gubernatorial election indicate that 60%
of registered voters actually voted in the election. If there are 21,800
eligible voters in Terrance County, how many people voted in the recent
qubernatorial election?
Answer:
11118 people voted
Step-by-step explanation:
Given
[tex]Eligible\ Voters = 21800[/tex]
[tex]Registered\ Voters = 85\%[/tex]
[tex]Voted\ Voters = 60\%[/tex]
Required
Determine the number of voters
First, we need to determine the number of registered voters.
[tex]Number = \%Registered\ Voters * Eligible\ Voters[/tex]
[tex]Number = 85\% * 21800[/tex]
[tex]Number = 18530[/tex]
Next, we determine the actual voters using
[tex]Voters = \%Voters * 18530[/tex]
[tex]Voters = 60\% * 18530[/tex]
[tex]Voters = 11118[/tex]
Hence, 11118 people voted
Suppose that you draw one card from a well-shuffled deck of 52 playing cards. What is the probability that the card that you draw is a black 7 or a black 8
The probability that the card that you draw is a black 7 or a black 8 is 1/13
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
So, the probability that the card that you draw is a black 7 = 4/52
So, the probability that the card that you draw is a black 8 = 2/26
Therefore,
the probability that the card that you draw is a black 7 or a black 8 = 4/52 - 2/26 = 1/13

because it's negative, the lowest number is the greatest number so
-5.25 is greater than -5.30
An automobile manufacturer claims that their van has a 46.4 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this van. After testing 140 vans they found a mean MPG of 46.0. Assume the standard deviation is known to be 2.6. Is there sufficient evidence at the 0.02 level that the vans underperform the manufacturer's MPG rating?
Answer:
The decision rule is
Fail to reject the null hypothesis
The conclusion
There is no sufficient evidence to conclude that the vans underperform the manufacturer's MPG rating
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 46.4 \ miles/gallon[/tex]
The sample size is n = 140
The sample mean is [tex]\= x = 46.0[/tex]
The standard deviation is [tex]\sigma = 2.6[/tex]
The level of significance is [tex]\alpha = 0.02[/tex]
The null hypothesis is [tex]H_o : \mu = 46.4[/tex]
The alternative hypothesis is [tex]H_a : \mu < 46.4[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{ \= x - \mu }{ \frac{\sigma }{\sqrt{n} } }[/tex]
=> [tex]t = \frac{ 46 - 46.4 }{ \frac{ 2.6 }{\sqrt{140} } }[/tex]
=> [tex]t = -1.8203[/tex]
From the z table the area under the normal curve to the left corresponding to
-1.8203 is
[tex]P(Z < -1.820 ) = 0.03438[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = P(Z < -1.820 ) = 0.03438[/tex]
From the value obtained we see that the p-value > [tex]\alpha[/tex] hence
The decision rule is
Fail to reject the null hypothesis
The conclusion
There is no sufficient evidence to conclude that the vans underperform the manufacturer's MPG rating

From the graph, [tex]y=mx+b[/tex] and m < 0 (The slope right here is less than 0.)
That means cut ( b ) and ( d ) choice, they both are wrong.
Now look at ( a ) and ( c ).
For ( a ) It's just f(x) = -2x but the graph that's shown here intercepts y-axis at (0,2). f(x) = -2x is just slope and intercepts y-axis at (0,0)
So the answer is ( c )
